Title: Controller for pwm inverter
Inventor: YANASE TAKAO
IPC: H02M7/48
Filed: 1984-10-15
Abstract: PURPOSE:To flow a sinusoidal current to an AC machine by providing a magnetic flux adjusting loop and PWM-controlling it by the loop. CONSTITUTION:A terminal voltage of an AC machine insulated via an insulating transformer 6 from a main circuit is integrated by a magnetic flux detector 7 to obtain stator magnetic fluxes phiR, phiS, phiT of the machine 2. Magnetic flux regulators 3a-3c respectively compare and regulate the detected magnetic fluxed phiR, phiS, phiT with the command values phi*R, phi*S, phi*T, and output a voltage command so that the magnetic fluxes coincide with the command value. A PWM pattern is generated by the comparators 4a-4c by the voltage command value, and applied to a PWM inverter 1. As a result, a stator magnetic flux coinciding with the magnetic flux command value is generated in the machine 2, and a preferable sinusoidal current is flowed to the machine 2.

Title: Liquid crystal display device
Inventor: FUKUDA NAOTO
IPC: G02F1/133
Filed: 1989-08-21
Abstract: PURPOSE:To eliminate crosstalks and to make display with a high grade in the high time division driving by decreasing the width and area of scanning electrodes. CONSTITUTION:The scanning electrodes S are formed to <= 0.15mm width and a driving circuit 4 executes the high time division driving of >= 1/150. The length of the scanning electrodes S is set shorter than 10,000/(width of the scan ning electrodes X the duty ratio of the high time division driving). Namely, the crosstalks are more hardly generated in the high time division driving as the scanning electrodes S are thine and the differences of display densities arise on the right and left of a screen by the direct influence of the high time division driving if the scanning lines are fine and long. The length at the time of, for example, 0.1mm width and 1/400 high time division driving is kept within 25cm in order to avert the above-mentioned influence. The display free from ghosts and crosstalks is executed in this way even at the time of the high time division driving.

Title: Heat treatment for substrate-coating film
Inventor: SHIRAKI HIROYUKI
IPC: H01L21/768
Filed: 1981-12-25
Abstract: PURPOSE:To remove irregularity in thickness, bubbles, and distortion from a coating formed by a rotational coating method and thereby to form a free of- bubble, homogeneous, fine, and flat film by a method wherein a substrate is subjected to ultrasonic vibration while under-going heat treatment. CONSTITUTION:Vibration of a vibrating piece is transmitted via a support 7 to a semiconductor substrate when the vibrating piece is fixed to the support 7 by soldering or brazing. Vibration is generally effective when it is applied simultaneously with heat. By way of example, an approximately 1mum-thick Al wiring on an SiO2 coating is rotationally applied with an approximately 1mum-thick coating of polyimide resin, which is followed by a 90-100 deg.C heat treatment for  30min in an ultrasonic heat treatment furnace generating a 49KHz frequency.  The ultrasonic wave reduces the difference in thickness between the upwind and  downwind portions. Air bubbles and distortion in thicker portions are also greatly reduced. The coating solidified in the first heating grows drier and stronger  after repeated treatment under 200 deg.C/30min and 350 deg.C/30min conditions.
